5 2156 Bony Fishes Beloniformes: Hemiramphidae HEMIRAMPHIDAE Halfbeaks by B.B. Collette, National Marine Fisheries Service Systematics Laboratory, National Museum of Natural History, Washington, DC, USA Diagnostic characters: Elongate fishes reaching 40 cm total length, 35 cm standard length with a prolonged lower jaw and a short triangular upper jaw (except in Oxyporhamphus similis). Nostrils in a pit anterior to the eyes. No spines in fins; dorsal and anal fins posterior in position; pectoral fins usually short; pelvic fins in abdominal position, with 6 soft rays. Lateral line running down from pectoral-fin origin and then posteriorly along ventral margin of body. Scales moderately large, cycloid (smooth), easily detached. Colour: these fishes live at the surface and are protectively coloured for this mode of life by being green or blue on the back and silvery white on the sides and ventrally. Tip of the lower jaw bright red or orange in most species. short triangular upper jaw nostril in open pit lower jaw typically prolonged lateral line pelvic fin Habitat, biology, and fisheries: Most species are marine, but some inhabit freshwaters. Omnivorous, feeding on floating sea grass, crustaceans and small fishes. Eastern central Atlantic species are all oviparous. Eggs with filaments that attach to sea grasses or algae. Halfbeaks are prone to leap and skitter at the surface and one offshore species, Euleptorhamphus velox leaps out of the water and glides like a flyingfish. Although at present these fishes are not of great commercial importance, most species are regularly found in local markets. The flesh is excellent and halfbeaks are utilized as food in many parts of the world. They are mainly caught with seines and pelagic trawls and utilized fresh, dried-salted, smoked and for fishmeal and oil. They are also important as bait for gamefishes like marlins. Similar families occurring in the area Belonidae (needlefishes): both upper and lower jaws elongate and armed with needle-sharp teeth. Exocoetidae (flyingfishes): lack the prolonged lower jaw characteristic of most halfbeaks; pectoral fins or both pectoral and pelvic fins enlarged and used for aerial gliding. both jaws elongate lack prolonged lower jaw Belonidae Exocoetidae
